I just installed Debian Stretch (Kernel 4.12.0-0.bpo.1-amd64) on my old Thinkpad T60 with an OCZ Octane SSD. Unfortunately after reboot, if started to behave strange: The system froze on nine out of ten tries to boot it. When it booted successfully, the SSD went to Read-Only after heavy load.

I don't know. I put it in "System Configuration" and someone moved it here

no!

Sorry, I was wrong here! It was crashing with the 4.9 kernel. Then I started a repair system, chrooted into the running system, installed the new kernel and it kept on crashing. Then I spend a night with forums and kernel-parameters and forgot that I installed the backport-kernel. I'll try later if libata.force=noncq also resolves the issue on 4.9.
